Your EAW loudspeaker normally requires no regular maintenance for normal use. However, you can do several things to keep your loudspeaker in good operating and cosmetic condition.

1.Testing: Periodically test your loudspeaker for proper performance. A simple test is to play a CD through it using well-defined, articulate, wide-range program material. Listen to ensure all drivers are working properly and for any evidence of distortion or other extraneous sounds. Test at several volume levels: very low, normal and high.

2.Mounting/Rigging: Any mounting or rigging hardware should be regularly inspected for security, wear, deformation, corrosion, and any other circumstances that may affect the load handling capability.

3.Cleaning: Cleaning the exterior of the enclosure will depend on the type of “dirt”. Dust, food spills or similar can usually be removed with a cloth dampened with water or a mild household cleaner. Avoid using any strong solvents as this may damage the finish.

4.Scratches or Dents: Minor scratches on the enclosure can be painted over with an outdoor latex paint or simply colored in with a “Sharpie” or artist’s marking pen. More serious gouges or dents should be sanded out, filled with wood putty and repainted. Black touch-up paint in pints (part #810050) or quarts (part #810049) is available from the EAW Service Department. Tips for repainting are on EAW’s website: http://eaw.com/pages/TechSupport/FAQs/RepaintInstructions.pdf.

Section 6 Troubleshooting

Loudspeaker difficulties usually fall into one of the following categories. The causes for each problem are listed in the most likely order of probability.

6 . 1 N o S o u n d o r L o w O u t p u t

1.Loudspeaker cables or connectors are mis-wired or faulty. Check all cabling. Refer to these instructions for correct loudspeaker cable connections. The best way to check a suspect cable is to swap it with a known good cable. Read the loudspeaker’s input panel to verify correct cable connections.

2.Electronic equipment is not turned on or level controls are not adjusted properly. Make sure that all equipment in the signal path is powered up and that all controls are set to appropriate levels for normal operation.

3.Loudspeaker is not working. Connect the loudspeaker cable to a known good loudspeaker leaving all equipment set to the same levels. If the problem disappears, the loudspeaker is probably not working. Contact EAW Service for appropriate troubleshooting.

1.The power amplifier is clipping. The signal level is exceeding the limits of your system and you must reduce the level.

2.Other electronic equipment is clipping. Ensure that no equipment in the signal chain is being overdriven. For example: input(s) or summing bus in the mixing console, equalizers, etc.

3.Driver(s) not working properly. Contact EAW Service for appropriate troubleshooting.
